Magic Fermions: Carroll and Flat Bands
Arjun Bagchi, Aritra Banerjee, Rudranil Basu +2
The Carroll algebra is constructed as the limit of the Poincare algebra and is associated to symmetries on generic null surfaces. In this paper, we begin investigations of…
Carroll fermions in two dimensions
Aritra Banerjee, Sudipta Dutta, Saikat Mondal
Carroll symmetry is a very powerful characteristic of generic null surfaces, as it replaces the usual Poincaré algebra with a vanishing speed of light version thereof. These symmet…
Bootstrapping the Kronig-Penney Model
Matthew J. Blacker, Arpan Bhattacharyya, Aritra Banerjee
Recently, bootstrap methods from conformal field theory have been adapted for studying the energy spectrum of various quantum mechanical systems. In this paper, we consider the app…
ModMax meets GCA
Aritra Banerjee, Aditya Mehra
A maximally symmetric non-linear extension of Maxwell's theory in four dimensions called ModMax has been recently introduced in the literature. This theory preserves both electroma…
From CFTs to theories with Bondi-Metzner-Sachs symmetries: Complexity and out-of-time-ordered correlators
Aritra Banerjee, Arpan Bhattacharyya, Priya Drashni +1
We probe the contraction from relativistic CFTs to theories with Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, using diagnostics of quant…
Boosting to BMS
Arjun Bagchi, Aritra Banerjee, Hisayoshi Muraki
Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, are intrinsically associated to null manifolds and in two dimensions can be obtained as an In{ö}…
